Edge Blend shows in render but not preview

I'm new to Poser and working with time constraints trying to create a ghost avatar. She renders fine, but the edge blend doesn't show in preview? Instead just a white block surface. Hence i'm stuck as i can't make animation or do anything. Any help is welcome. Thank you so much.

It may be one of the lights which causes this.
If you load the poser default scene (with andy) and apply the shader to andy - does that work?
If that does not work either, it may be a graphics opengl driver issue
What video card do you have?
